The MicroCT Multi Disk phantom (after
Defrise) has long been well established as the
test object for demonstrating artefacts
occurred by all kind of approximate
reconstruction algorithms.
The QRM-MicroCT-MultiDisk phantom after
Defrise consists of eight high-density circular
disks equally spaced at 3 mm apart parallel to
the axis of rotation. These disks are separated
by low-density disks showing up as darker
material. The phantom is completed on either
side by 10 mm of PMMA.
Standard phantoms are scaled down from the
diameter of an average human trunk (32 cm)
to that of a fat mouse or lean rat (32 mm).
Other dimensions as well as inserts with
substances other than specified here can be
produced upon request.
